ERRE

If the discriminant of a quadratic equation is 4, which statement describes the roots?
O There are two complex roots.
O There are two real roots.
O There is one real root.
O There is one complex root.

Answer 1

An equation can have 2 real roots if the discriminant is 4.

Answer 2

B) There are two real roots

Explanation:

If the discriminant
`b^2-4ac>0`, then there are 2 real roots. Thus, since
`4>0`, there are indeed two real roots.
